[Serusers] Bug with SER 9.0.2?

Alberto Cruz acruz at tekbrain.com

So should I have to give the same treatment to method=="CANCEL" as 
method=="BYE"?
i.e.:
        if (client_nat_test("3")) {
                setflag(7);
                force_rport();
                fix_nated_contact();
        };

Regards
